I'll try to be as accurate as possible about things. Firstly yes I am overweight, but NO I legitimately do not believe it to be the cause. Why?
Before the pain began I was active; walking up to 5 miles without even needing to stop, hiking, camping, I am also a carer for 2 people. I am also currently losing weight and have a history of cancer.
Now? I can't even complete the washing up without having at least 1 'sit down' in the middle of it. This is not weight-related, this is something else, I just don't know what.
Painkillers aren't helping (so could be nerve related)
So please, if you're just going to judge me, and assume that I am fat, lazy and spend my days lying on my back eating cake, please save your energy, thank you. Apologies if this sounds harsh or defensive, but I am SO tired of people dismissing what could be legitimate health problems with 'lol ur fat go for a walk' solutions.
When sitting, I am pain-free with a fully-mobile back. I can twist, bend and stretch with no pain or restriction.
When I stand and move about, the pain begins building slowly and all the lower back muscles tense and seize up to the point I am in crippling agony. This happens over several minutes; worse if I am carrying bags. The pain 99% of the time is on the left, with a very specific 'hot spot' being just to the left of my spine.
The instant I sit down, the pain disappears entirely and I am once again fully mobile. The act of sitting down feels like having a really sore stretch but it vanishes instantly.
I cannot find ANYTHING online about this exact type of pain. It doesn't seem to be spinal but rather muscular or nerve related.
Also on occasion, it's almost like I can't walk properly. Like my step and posture are all out of whack and I can't quite figure out why or how to stop walking weird.
